mobile phone batteries

As energy source, battery is one of the most important accessories for mobile phones. Nowadays, Ni-Cd battery, which born in black-white display mobile phone generation, has exited the mobile phone batteries market, and NI-MH battery also has little demand. The color display generation leads to wide application of Li-ion battery (Li-ion), which includes lithium ion battery (LIB) and lithium ion polymer battery (LIP). As the most demanded battery, Li-ion covers 80％ of the market share, while that of NI-MH battery only covers 20％. Moreover, the new generation of LIP is becoming more and more popular for its advantages and with a market share of 12％-14％. After several years' development, the global Li-ion battery industry has been monopolized evenly by China, Japan and South Korea. This pattern will last for quite a long time since each of the three countries has its own characteristics and advantages. In recent years, China has made great achievements in Li-ion battery industrialization. The sales revenue of Li-ion battery has exceeded that of Ni-Cd and NI-MH Battery. With the mobile phone batteries market shrinking of Ni-Cd and NI-MH Battery, the popularities of consumer electronic products and mobile electronic products such as mobile phone, digital camera, PDA and camcorder etc, as well as the huge application potentials of Li-ion battery, the market demand of Li-ion will increase with a relatively rapid growth rate in the future.
